This invention relates to an improvement in machines for crimping caps on bottles. It is particularly designed for use in machines for automatically crimping caps of paper,

tinfoil, or the like, on bottles, such for instance as the machine disclosed in the copend- 'ing application of Rupert E. Rundell, S. N. 100,398, filed April 7, 1926. In machines or" this type, a series of crimper heads are pro gressively moved above a series of correspondingly moving bottle supports. These bottle supports are raised and lowered to push the top of the bottle, after a cap has been fed thereto, into the crimper head, and are thereafter lowered to withdrawthe capped bottle from the head. The-bottle is subsequently removed from the machine by suitable delivery means. Occasionally'because of a torn cap, an oversizebottle, or some other ie crimper head fails to. release the reason, tl

bottle and after lowering of the bottlesupport, it is left hanging in'the head. When this occurs, the bottle will be carried beyond the point at which it would normally leave the machine and is liable to injure the machine and cause breakageQ p The main object of the present invention is to prevent this possibility by providing means for automatically stopping the machine when a bottle thus sticks in the crimpcr head; i r

With this and other objects in view, the invention consists in certain constructions and combinations which will be hereinafter de scribed and then set forth in the hereunto appended claims.

' the headafter crimping, a controlmember positioned between the path of movement of said head and the tops of'bo withdrawn from said head for ttles normally the purpose of engaging only bottles which stick in the head,

and means actuated by said con trol member to automatically stop the machine when a. bot-, tle stuck in said head engages sald member. In the best constructions, sa d means 1nchides a drive clutch for the machine, confore, should not be restricted structure of the machine. shown to the precise and described.

Referring to the drawings, the present dev vice: is illustrated attached to the frame 5 o theniachine disclosed in the above mentioned copending application, only s same being shown as is nece 0 much oi -the ssary to 1llus-' trate thelpresent device. On this frame 5 there ismounted an upright support 6 carrying brackets 7 and 8 in which is rotatably mounted a vertical shaft 9. The upper end of the shaft 9 carries fixedly mounted thereon an arm 10, havingadjustably mounted o n its free end a horizontal control linger 11. The

arm 10 is located on said sha height that the control finger 1 ft 9 at such a 1 is located between the path of movement of the crimpcr head 25-26 and the tops of the bottleswhen moun withdrawn from the crimper head, asshown in dottedlines in Fig. 2. Y Y

' A horizontally extending la is rigidly secured to the lower e 9 and is-pnlled by spring 13 justable stop screw 1 1 tension. of bracket 8. When tch element 12 rid of the shaft againstfa'n ad-. ted in an expulled to this position, the latch engages a catch 15 on abar.

o. This bar isimounted f0 r longitudinal movement towards aclutch shifting-lever 21,

' by means of apair .oflevers 17 ed on studs 19- and brackets and 18 mount- 20 secured to trainee. The lever 21 is pivoted onshaft 22 and operates .the clutch 23 on the m shaft 24: of the machine. v

During the operation of t ain drive he bottle cap crimping machine, the bottle B rests on the plunger 28 on turret 27 below the crimper head provided with crimping fingers 25a simultaneously operated by a ring 25, which plunger is raised to push the bottle into the cap support 26 of the crimper head. After a cap has been crimped on the bottle by the head which. is progressively revolved in the direction indicated by the arrow in Fig. l, the plunger 28 is lowered and this normally withdraws the bottle from the fingers 25a of the crimpcr head to the position shown in dotted lines in Fig. 2. As will be seen from Fig. 2, the finger 11 is located below the crimping lingers 25a and above the position of the tops of bottles when normally with: drawn from saidtin 'ers and along the path of the progressively moving crimper head, so that the crimping fingers pass above the control finger 11 and the normally withdrawn bottles pass below the control finger without disturbing said control finger.

If, however, for any reason the crimping fingers fail to release the bottle so that same hangs therein, as shown in full lines in Fig. 2, the control finger will extend across its path as it is carried along by the moving crimper head and the bottle will engage and move said control finger, thereby swinging the arm 10, the shaft 9and the latch element 12. The latch 12 will then disengage from the catch 15 on the bar 16, whichis urged against a pin 32 on the clutch lever 21 by the spring :29, but normally held in abeyance by s-aaid latch. The bar 16 will, therefore, strike the pin 32 of the lever 21 and throw the lever, disengaging the clutch 23. The forward mo tion of the bar 16 is limited by lugs 33 of levers 17 and 18, which engage the sides of the brackets 20 and recoil of the bar is prevented by the spring 84; attached to bar 16 and lever 18, so thatthe retarding force exerted by said spring will increase toward the end of the stroke of the bar as tension of the spring 29 decreases and by l'iinging spring anchoring lever 30 at 31. This hinging of lever 30 tends to eliminate recoil through preventing back compression or a back compressional surge in the spring.

It will, therefore, be seen that the invention provides means for automatically stop-' ping the machine vhen the crimper head fails to release a bottle, which will not in any way interfere with the normal operation of the machme, and which 18 certaln in operation.

lVhat is claimed is:

'In'a bottle capping machine, the com biuation with a progressively moving crimper head for crimping caps 011 bottles, of a support for the bottles operable to lower the capped bottles from the head after crimp ing, a control member positioned between the'path of movement of said head and the tops of bottles normally lowered from said head for the purpose of engaging only bottles,

which stick in said head, and means actuated by said control member to stop the machine when a bottle engages said member.
